01
Mechanism
Aerodynamic moments depend on the relative locations of the center of gravity, lifting surfaces and stabilizers. A restoring moment indicates positive static stability.
02
Aircraft response
Center-of-gravity changes affect trim, control forces and stability margins. Stability and available control authority are related but distinct.
03
Context & interpretation
Static stability describes the initial tendency; dynamic stability describes the subsequent motion over time. Approved loading envelopes address several constraints simultaneously.
